System and Apparatus for Wearable Exercise Apparel Using Integrated Resistance Bands

ABSTRACT

A wearable exercise suit is taught which uses the elongated configuration of the raglan sleeve to ensure a more intense exercise experience. The invention teaches a long sleeved raglan shirt having resistance bands included therein for exercising the human muscles. The resistance bands are connected at the wearer&#39;s wrists and at shoulder locations. Tension is created in the resistance bands when the wearer moves his appendages. In one embodiment, the resistance bands are connected at multiple locations on the raglan sleeve to further increase tension and resistance to movement.

FIELD OF INVENTION

This invention relates to a wearable exercise suit. More particularly,the invention relates to the field of wearable exercise suits whichimprove overall health by resisting the natural movement of the humanbody.

BACKGROUND OF INVENTION

People all over the world are finding less time throughout the day towork on their physical fitness. Consequently, those wishing to fitexercise into their daily routine must use methods which are bothconvenient to use and provide an efficient calorie burn. In some cases,a well-designed wearable exercise suit would serve both needs.

Consumers today have several different variations of the wearableexercise suit from which to choose. In some instances, the exercise suitmay have a system or method located inside its fabric as a means forresisting the natural movement of the wearer. The built-in system ormethod may be tension straps or resistance bands. It is well known howresistance bands function. Particularly, tension in resistance bands maybe created when the force of the wearer's movement stretches theresistance band out of its resting/relaxed position. The wearer mustalso exert force to prevent the resistance band from returning to itsrelaxed shape. The tension in the resistance bands necessary for anefficient exercise experience may be appropriately correlated to theforce and direction the user exerts on the resistance band.

In a typical sense, when totally included with an exercise suit, theresistance bands may be anchored to the resistance suit at itsrespective ends. For example, the resistance band may be fixed at eachof its ends. In use, the tension straps are stretched as the userexercises. In a typical case, when the user exercises, the movement ofthe user's appendage stretches the resistance band creating tension inthe band as the resistance bands move away from each other. The degreeof force required by the wearer to stretch the resistance band can betranslated to calories burned and muscles toned. In other cases, themeans for resisting the natural movement may be a weighted material(“weights”) that requires the wearer to exert additional effort to movehis limbs.

Unfortunately, prior art exercise suits have shortcomings that workagainst the need for convenience and efficiency. For example, U.S. Pat.No. 5,937,441 (“the '441 Patent”), issued Aug. 17, 1999 to Raines, is ofthe variety of exercise suits using weights. The '441 Patent teaches aweighted exercise suit used in athletic training, physical therapy, andmuscle toning. The suit in the '441 Patent includes weights attachedthereto. The suit in the '441 Patent is highly inconvenient to thewearer because he/she must interrupt her exercise to change the weightsbefore continuing.

U.S. Pat. No. 4,910,802 (“the '802 Patent”) is typical of anotherexercise suit that uses a plurality elastic bands to exercise each humanappendage. The '802 Patent teaches an exercise suit that uses elasticbands (“resistance bands”), wherein the tension in the band is adjustedby way of buckles. The '802 Patent suffers from the same problem as the'441 Patent in that the wearer must interrupt their exercise routine toadjust the tension of the suit. Additional, since the suit in the '802Patent uses buckles, it is prone to breaking from normal wear and tear.

U.S. Patent Application Publication No. 2013/0067628 A1 filed May 9,2012 by Harb (“the '628 Application) is another example of an exercisesuit incorporating elastic bands. The elastic bands are removable andinclude loops that loop around the thumbs of the wearer's hands. Theloops serve as a resistance band anchor from which the band is stretchedwhen the wearer moves. Unfortunately, the teaching in the '628Application may interfere with the natural movement of the wearerbecause it is typically not natural to have a loop between the thumb andforefinger. Additionally, the use of the loops promote an unorthodoximproper footing/stepping resulting from the looping anchor of the feetof this suit. Such unorthodox stepping can severely interfere with thesmooth motion needed for some exercise routines.

Prior art suits that use resistance bands also have the additionalproblem that the placement of the bands points of restraint often pullat the seams of the garment, thereby weakening the integrity of thegarment. For example, where the resistance band is anchored nearer tothe wearer's deltoid, the resistance band pulls at the shoulder seam ofthe garment weakening and compromising the seam and interfering with thewearer's workout. Consequently, when the garment is compromised, so isthe wearer's exercise routine.

Although the above noted suits may be effective in one respect, theyhave shortcomings in that, as mentioned, the suits are inconvenient touse, don't provide the proper calorie burn because of the integrity ofthe suit is compromised because of the design. The present inventionsolves both of those shortcomings and provides advantages not found inthe prior art exercise suits.

SUMMARY OF INVENTION

The present invention teaches an exercise shirt configured to be worn ona human torso. that provides resistance to the wearer's natural movementfor exercising the wearer's muscles. The exercise shirt of the presentinvention comprises a raglan shirt. The raglan shirt may be shaped orconfigured like a tight-fitting shirt. In an exemplary embodiment, theraglan shirt may be configured as a compression shirt. The raglan shirtof the present invention may be a long-sleeved shirt.

The raglan shirt may include narrow passageways therein at predeterminedlocations, wherein at least one of the narrow passageways has aresistance band included therein. The resistance bands may be fixed, orsubstantially fixed at at least two locations within the passageway. Forexample, according to the present invention, a resistance band may befixed at the first end and second end of the resistance band byrespective resistance band connectors. Additionally, the resistance bandmay be substantially fixed at a third or additional connectors locatedin between the respective connectors for the first end and second end ofthe resistance band. In one embodiment, the resistance band may beaffixed above the wearer's trapezius. In another embodiment, theresistance band may be affixed substantially midway between the wearer'slevator scapulae and the wearer's trapezius.

In one particular embodiment of the invention, the tension necessary forefficient exercising may be predetermined by selecting a resistance bandhaving a predetermined tension or resistance to stretching. In oneexample, the bands may include light, medium, heavy or very heavyresistance. A user may select a resistance band suitable for highrepetition low tension (i.e., resistance) to tone and maintain hisphysical fitness. On the other hand, the user may select a high-tensionband if the intent is to do low repetitions to build muscle. In yetanother embodiment, the tension necessary may be chosen according to amethod which selects the resistance bands based on some predeterminedcriteria related to the wearer's physical fitness goals.

In yet another embodiment of the invention, the tight-fitting shirt maybe comprised of at least one raglan sleeve. The raglan sleeve includes asleeve that does not have a seam on the topside of the wearer'sshoulder. Instead, the topside of the sleeve is conjoined with thecollar of the shirt. The raglan sleeves of the present invention furtherinclude narrow passageways for receiving the resistance bands. A firstnarrow passageway may traverse from a first location at the wrist of thesleeve to a location substantially midway across the trapezius area ofthe shoulder location of the sleeve. A second passageway may furthertraverse from the location substantially midway across the trapeziusarea of the shoulder and progress to a second location at the wrist ofthe sleeve. As used herein, the trapezius area of the sleeve, or thetrapezius area of the shoulder may mean the area of the raglan shirtwhich would rest substantially above a wearer's trapezius when the shirtis worn. The trapezius area of the sleeve, or the trapezius area of theshoulder may mean the area substantially midway between the wearer'slevator scapulae and the wearer's trapezius.

According to various aspects of the invention, one or more of theresistance bands may be included in the passageways. In one embodiment,a single resistance band may be fixed at the first location at thewrist, traverse through a location substantially midway across thetrapezius of the shoulder and terminate at a second location at thewrist. In another embodiment, two resistance bands may be included inthe narrow passageway to provide resistance when the wearer's arm isbending and unbending at the elbow. In this embodiment, a firstresistance band may be fixed at a first location at the wrist and fixedat a first location substantially midway across the trapezius of theshoulder. A second resistance band may be fixed at a second location atthe wrist and a second location substantially midway across thetrapezius of the shoulder. In another embodiment, the first and secondresistance bands may be of the same or different resistance.

In yet another embodiment, the raglan shirt may be configured so thatmultiple bands may exercise one side of the wearer's arm. The raglanshirt may include a first lower arm resistance band within a narrowpassageway, wherein the lower arm resistance band may be fixed at alocation at the wrist, and wherein the lower arm resistance bandtraverses over a first side of the wearer's forearm, and wherein thelower arm resistance band is fixed to a first location below thewearer's elbow location and further affixed a first location above thewearer's elbow location.

In yet another embodiment, the present invention includes an exerciseshirt including a first and second raglan sleeve that are similarlyconstructed as herein described with respect to the first raglan sleeve.

DETAILED DESCRIPTION

The brief description of exemplary embodiments of the invention hereinmakes reference to the accompanying drawings, which show the exemplaryembodiments by way of illustration and its best mode. While theseexemplary embodiments are described in sufficient detail to enable thoseskilled in the art to practice the invention, it should be understoodthat other embodiments may be realized, and that logical and mechanicalchanges may be made without departing from the spirit and scope of theinvention. Thus, the description herein is presented for purposes ofillustration only and not of limitation. Indeed, for the sake ofbrevity, the connecting lines shown in the various figures containedherein are intended to represent exemplary functional relationshipsand/or physical couplings between the various elements.

Furthermore, for the sake of brevity, traditional constructions ofraglan shirts will not be described herein. The raglan shirt of thepresent invention may be textile. The raglans shirt may have portionsthat are customary for raglan shirts. That is, the wrist, shoulder, neckand waist locations, of the raglan shirt are at the conventionallocations for raglan shirts. Raglan shirts do not include a seam runninglaterally along the wearer's shoulder. Further still, by shoulderlocation what may be meant is the location substantially midway abovethe trapezius. Additionally, by shoulder location what may be meant isthe location midway between the wearer's levator scapulae and thewearer's trapezius. All of the portions and locations of the raglanshirt as described (e.g., wrist, elbow, shoulder, levator scapulae, andtrapezius) may be connected each to the other by textile material thatis configured to be adjacent to the corresponding portions of thewearer's body.

By tight fitting what may be meant is that the raglan shirt of thepresent invention (either shirt, pants, or both) fits closely to thewearer's body such that the wearer's physical outline may be easily seenby the casual observer. The suit may be tailorable to a particularwearer's body composition (e.g., shape, size, fat composition, etc.).The suit may also be configured in accordance with the wearer's desiredworkout goals. For example, the length, thickness and resistance of theresistance bands included in the suit may be chosen according to thewearer's physical fitness goals. For example, the wearer may choose thelevel of tension/resistance of the resistance band according to hisworkout. A resistance band with more resistance or a higher resistancerating may provide a more rigorous workout than a resistance band with alower resistance/tension rating. A thicker resistance band may be chosento further increase the resistance bands resistance/tension rating.

In particular embodiments of the invention, the resistance bands areanchored at at least two locations to ensure that tension is created inthe resistance band when the wearer of the exercise suit moves. By“anchored” or “connected” what may be meant is that an end of theresistance band is immovably fixed to the raglan sleeve by a suitableconnector. A suitable connector is one that may immovably fix theresistance band by conventional means such at sewing in or to, rivetedin or to, gluing in or to, coupled in or to the raglan sleeve, or anysuitable means of connecting a resistance band to a sleeve.

In other particular embodiments, a portion of the resistance band mayhave restricted movement. That is, the movement of a portion of theresistance band is slowed or retarded by, for example, a restrictiveconnector that permits restricted movement of the resistance band. Therestricted movement does not totally immobilize the resistance band, butdoes restrict movement due to the friction experience between therestrictive connector and the resistance band when the band expands. Inanother exemplary embodiment, the restrictive connector alters thedirection in which the resistance band is stretched.

The resistance band may be anchored by a first connector at a first endof the resistance band and also anchored by a second connector at asecond location of the resistance band. In some instances, the secondlocation may be the second end of the resistance band. In anotherembodiment, anchored may mean that although the resistance band is notimmovably fixed by the connector, a portion of the resistance bandexperiences sufficient friction to ensure that the entire resistanceband may be stretched and tension created. At least one point of theresistance band between the first and second ends of the resistance bandmay be immovably fixed or substantially immovably fixed by theconnector. By substantially immovably fixed what may be meant is thatthe movement of the resistance band is substantially restricted by aresistance band connector.

Furthermore, various embodiments of the invention make reference toparts of the wearer's body when discussing the locations of theresistance band connectors. This is done to indicate where, on theraglan sleeve, the connector may be found, relative to the wearers'bodies. For example, where the connector is described with reference tothe shoulder location (e.g., a shoulder resistance band connector), theconnector may be connected on the portion of the raglan sleeve whichrest on, is in communication with, or is adjacent to the wearer'sshoulder, such as, when the raglan shirt is being worn. Similarly, wherethe connector is described with respect to the wearer's wrist or elbow(e.g, resistance band connector at the wrist location), the connectormay be connected to the portion of the raglan sleeve which is incommunication with, rests on, or is adjacent to the wearer's wrists orelbow location, such as when, the raglan shirt is being worn.
